OBJECTIVE: Although cor pulmonale due to chronic lung disease was not uncommon, there was uncertainty in its diagnosis due to the difficulty in measuring functional and anatomical changes of right heart and pulmonary vascular system. Among various non-invasive diagnostic methods presented so far, no ideal standard diagnostic criterion has been established. The authors attempted to know positive diagnostic ratio of cor pulmonale and to study the presence of the relationship between these diagnostic criteria when electrocardiographic and echocardiographic diagnostic criteria for cor pulmonale were applied to the patients with chronic lung disease. And we investigated the usefulness of echocardiogaphic diagnostic criteria for the diagnosis. METHODS: One electrocardiographic and two echocardiographic diagnostic criteria were applied to 38 patients with chronic lung disease(21 pulmonary emphysema and 17 chronic advanced pulmonary tuberculosis) for the diagnosis of cor pulmonale. Comparison was also made in their relationship. Then pulmonary artery diameter, measurement of pulmonary function test and echocardiographic examination and radio-nuclear right ventricular ejection faction were compared between the groups to ensure each criterion was satisfied. RESULTS: 1) When the three diagnostic criteria for confirming the cor pulmonale, electrocardiographic rriterion(right ventricular hypertrophy), right ventricular dimension criterion(right ventricular end-diastolic dimension>25mm, RVDd>25mm), and right ventricular wall thickness criterion (right ventricular wall thickness>6mm, RVWT>6mm) were applied to the patients, the positive rate were 32%(12/37), 30%(10/33) and 17%(6/36) respectively. A statistically significant correlation between electrocardiographic criterion and right ventricular wall thickness criterion was found to exist. 2) Various parameters of pulmonary function test and echocardiographic examination were compared in the patient groups with and without cor pulmonale when each non-invasive diagnostic criterion was applied to all patients. Followings are the results. (1) In the positive group on electrocardiographic criteria, vital capacity, forced vital capacity, and arterial oxygen tension were significantly smaller than in the negative group on electrocardiographic criterion(p<0.05), and the echocardiographic parameters of right ventricle, ie. end-diastolic area, end-systolic area, end-diastolic dimension, end-systolic dimension, mid-ventricular short axis and maximal short axis in positive group were significantly larger than in the negative group. (2) In the positive group on right ventricular diastolic dimension criterion(RVDd>25mm), percentage forced expiratory volume in 1 second and forced expiratory flow 25-75% were significantly smaller than in the negative group on right ventricular diastolic dimension criterion. (3) In the positive group on right ventricular wall thickness criterion(RVWT>6mm), vital capacity, forced vital capacity, forced expiratory volume in 1 second, forced expiratory flow 25-75% and arterial oxygen tension were significantly smaller than in the negative group on right ventricular wall thickness criterion. CONCLUSION: When several non-invasive diagnostic criteria for cor pulmonale were applied to the patients with chronic lung disease, there were some differences in its positive diagnostic ratio depending on the applied diagnostic criteria. There was also a statistically significant correlation between electrocardiographic criterion and right ventricular wall thickness criterion. When each diagnostic criterion was applied to the patients, significant differences were found in several parameters resulted from pulmonary function test and echocardiographic examination based on presence or nonpresence of cor pulmonale. But no difference in the ejection fraction measured by radio-nuclear method was shown between cor pulmonale group and non cor pulmonale group. Consequently it was suggested that applying echocardiographic criteria in addition to electrocardiographic criterion for the diagnosis of cor pulmonale in the patients with chronic lung disease is clinically useful.

It is likely that the peroneus longus tendon acts as a structure resisting the varus force upon the first column of the foot. Our study was designed to examine the possibility that absence of the peroneus longus insertion into the first metatarsal and first cuneiform will destabilize the first metatarsal. The fresh frozen cadaveric specimens of the lower leg were obtained. There were six right feet. The specimens appeared normal visually and roentgenographically. The tibial remnant was rodded by an intramedullary rod and the sprcimen was positioned in a specially designed rig so that standing position of the foot was simulated. The tibia was then loaded with twenty pounds. To obtain reproducible radiographic landmarks radioopaque beads were implanted underneath the level of the cortex through small drill holes in the following location : First metatarsal (one bead in the head, another bead in the base). The second metatarsal (again one bead in the head, on e bean in the base). To simulate the contraction of the peroneus longus muscle a suture was placed into the proximal end of the tendon, brought through two pulleys and loaded with a five pound weight. To create a varus force on the first metatarsal a stab incision was made over the base of the first metatarsal at its medial aspect and a suture was passed through the base of the first metatarsal. The suture was guided over a pulley and loaded with ten pounds. The second metatarsal head was fixed to the bottom of the rig with a smooth Steinmann pin. At this point an AP roentgenogram was taken of the footto assure proper positioning of the foot. Thereafter, the soft tissue between the first and second toe were cut sequentially : (1) Transection of the skin of the first web space both dorsally and plantarly. (2) Transection of the adductor hallucis tendon and the intermetatarsal ligament. (3) Transection of the peroneus longus tendon at its insertion. Each step in the transaction of the soft tissues was followed by another X-ray examination. In each roentgenogram the proximal and distal beads in the first and second metatarsal were connected by a line and the angles between those lines were measured. The results were statistically analyzed with the Friedman Chi square test between each step of the ten feet. Following the first and second step angular changes are not significant. Following the final step, adding release of the tendon insertion of the peroneus longus, the angle changes from 15.95 to 20.55 degrees (difference 4.60 degrees) and this is significant (p < 0.05).

BACKGROUND: The pathogenesis of confluent and reticulated papillomatosis(CRP) is still unknown, although many theories have been suggested. It is stressed that abnormal host response to colonization of pityrosporum orbiculare might play a role in the pathogenesis of CRP, but is not completely understood. Frequently, we have observed bacterial colonies in the stratum corneum and, especially, within the hair follicles from biopsy specimens of patients with CRP. In addition, successful treatment for CRP with minocycline, a derivative of tetracyclines, has been reported continuously. OBJECTIVE: The purpose of this study was to document the possible association of bacterial factors in the pathogenesis of CRP and to elucidate the effectiveness of minocycline. METHODS: We performed Brown and Brenn gram staining in 12 biopsy specimens, bacterial cultures, identification of microorganisms and antibiotics sensitivity testing including minocycline. We administered oral minocycline with an initial dose of 100mg per day for 1 to 3 months and a maintenance dose 50mg per day for I to 2 months, then evaluated the response of treatment. RESULTS: 1. On Brown and Brenn staining, the gram positive bacterial colonies that stained dark bluish or nearly black were observed within the infundibulum of hair follicles in 10 out of 12 biopsy specimens(83.3%) and on the keratotic invagination of stratum corneum in 11 out of 12 biopsy specimens(91.7%). 2. Histological features of regions where bacterial colonies were observed showed, hyperkeratosis and keratotic invagination on the stratum corneum in all cases. Hyperkeratosis(66.7%), parakeratosis(16.7%), inflammatory cell infiltration(25.0%), perifollicular fibrosis(33.3%), and abnormal keratin in sebaceous ducts(50.0%) were shown in hair follicles. 3. In anaerobic cultures, no bacteria was grown. In aerobic cultures, staphylococcus species were identified in 6 cases, streptococcus viridans in one case, sternotrophomonas maltophilia in one case. In the susceptibiliity test, minocycline was sensitive in 7 from 8 cases. 4. The therapeutic response to minocycline was observed within one month in all cases, and the time to clear the lesions was 1/2 month in 2 cases, 1 month in 4 cases, 2 months in 5 cases, 3 months in one case, respectively. CONCLUSION: Form these results, we suggest that bacterial factors may play an important role in the pathogenesis of CRP and that the action mechanism of minocycline in the treatment of CRP may be due to antibacterial effects.
